RPI-HQ contrast with vs without AWB question

[khobar95]

I have a RPI-HQ cam that I'm trying to tweak, and I noticed a dramatic difference when I switch AWB on - contrast is horrible. These two shots were taken yesterday during monsoon, so it's cloudy, but the difference is striking. I turned AWB on because my clouds were coming up orange. I have been tweaking the red and blue manually, but all I've managed is to turn the shots green. Not sure where to go next. Thanks!

@khobar95 Please do the following with AWB on:

sudo systemctl stop allsky
sudo truncate -s - /var/log/allsky.log
# change the **Debug Level** to 4 in the WebUI, then click the "Save Settings" button

After a few exposures, attach /var/log/allsky.log.

You can then reset Debug Level to what it was before.

This won't fix anything, but should give me information on what's happening.

Thanks Eric,

How long should I leave it with debug 4, and should I switch AWB on and off?

Thanks again!

@khobar95 You can set the Debug Level back at any time. I just wanted the additional information it added to the log file.

I suggest trying with AWB on and off. I'd guess you'll have better luck with it off. The next version of Allsky will support daytime and nighttime AWB settings.

Okay, here is a log file. I did make changes to camera settings to see if they produced anything useful. At some point, things went south so I rebooted the Pi.

Thanks again,

@khobar95 On Bullseye, the "normal" Brightness is 0 and the range is -1.0 to 1.0. Try setting it to 0 for day and night. The "normal" Saturation is 1.0. 0 give a black and white image. There is no upper limit but at some point the pictures start to look weird.

I don't know how those relate to Auto White Balance.

I was going to ask what Bullseye was - I'd seen mention of it but thought no, I'm running Debian Lite. LOL - I see now that is Debian Bullseye. So, my numbers are out of whack!

Thanks!

I changed the numbers and then enabled AWB and wow, dramatic difference! Obviously bright sunny daylight now, but I'm excited to see how it goes later on!

@khobar95 Paul, I'm glad it's working. The next Allsky release will show minimum, maximum, and default that are specific to the camera model you have, so the problem you had should go away. And the WebUI will only show settings that apply to your camera, e.g., ZWO doesn't have Saturation so it won't be shown to those users.

Every time a new major release of Linux comes out it gets a name like Buster, Bullseye, etc. Compared to Windows 8, 10, 11. Same idea. I'm pretty sure MacOS uses names instead of (or in addition to?) numbers.

[khobar95]

I assumed incorrectly, and, well, you know what they say about assume, except there was only me. ;)

Thank you so very much for your help!

Same here! Is there a description how to install the development version? Regards Urs iPadPro

@nacho3g, @WirthmU, I'm hoping we'll be ready for user testing of the new version of Allsky and the Allsky Website within a month.
The new Allsky now include the WebUI since it is used more heavily now. I'll put up a Discussion item requesting users to test, and it will include instructions for how to get the test version.

Thanks for your interest!
